Though the Kindle is cheaper, is it strange I want to support Barnes & Noble?

I love books. I love Barnes & Noble. I love being there.
I am thinking about buying a Nook because B & N makes it, and I would be giving them my business instead of Amazon. I saw what happened to Borders, and I most definitely do not want to happen to Barnes & Noble.
The Kindle is $20 cheaper than the Nook, and there are a lot of books you can get cheaper than on the Nook, but although the Kindle is better for my wallet, I want to support B & N because I don’t want them to go out of business.
Is that stupid?
Would it be unwise to go with the Nook just because I like the store it’s from?
